The trailer, which is just over a minute and a half long, gives us an even better look at Gyllenhaal's character Lou, who takes on a job doing freelance crime reporting for a television network that, apparently, gets him into a lot of trouble and possible danger. It's a role that Gyllenhaal has clearly put his all into, and it shows — judging by the trailer, Gyllenhaal has immersed himself in the character, and he even lost a reported 20 pounds to get into the role.

Nightcrawler, which is the directorial debut of The Bourne Legacy co-writer Dan Gilroy, is set to hit theaters October 17. Check the trailer below.
